There was (is?) a time where if you replaced the tranny fluid with anything BUT the exact Chrysler one, it would kill it dead pretty quick. Some people would buy up minivans with dead transmissions at 80k miles or whenever the quick lube place told them to flush the tranny, then clean it out and put the right fluid in and it'd work fine again.
My mom didn't even get one home from the dealership when it seized up on the highway. Something about the solenoid pack but don't take my word for it, I was all of 8.
